public transient OEMM.Node parent

Parent node.

isLeaf

public transient boolean isLeaf

Flag set when this node a leaf.

file

public transient java.lang.String file

File containing vertices and triangles.

counter

public transient long counter

Counter. This is a temporary variable used by some algorithms.

leafIndex

public int leafIndex

Constructor Detail

OEMM.Node

public OEMM.Node(int s,
                 int i0,
                 int j0,
                 int k0)

Creates a new leaf.

Parameters:

s - cell size

i0 - 1st coordinate of its lower-left corner

j0 - 2nd coordinate of its lower-left corner

k0 - 3rd coordinate of its lower-left corner

OEMM.Node

public OEMM.Node(int s,
                 int[] ijk)

Creates a new leaf.

Parameters:

s - cell size

ijk - coordinates of an interior point

Method Detail

setPathComponents

public void setPathComponents(java.util.ArrayList<java.lang.String> dir,
                              int octant)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getMaxIndex

public int getMaxIndex()

This methods calculate mexIndex of OEMM.Node. There is probably back with setting of maxIndex value because maxIndex < minIndex. It is sufficient compute getMaxIndex(n) := minIndex(n) + |maxIndex(n) - minIndex(n)|

Returns:

correct value of maxIndex
